* java/math/BigInteger.java
	* gnu/gcj/math/MPN.java (rshift0): New method handles zero shift count.
	(rshift(int[],int[],int,int):  Removed - not needed.
	(gcd):  Use rshift0 rather than rshift.
	* java/math/BigInteger.java (setShiftRight):  Likewise.
	(divide):  Simplify by using rshift0.
	(divide):  Zero-extend results if high-order bit set.
